2 Claims. (Cl. 25-131) This invention relates to concrete forms and moreparticularly it relates to an improved she-bolt form spacer forassembling she-bolts to a concrete form construction. The invention isprimarily directed to an improved shebolt form spacer construction forlocating the inner end of the she-bolt with respect to the inner face ofthe sheathing. lThe invention is also directed to the utilization of theshe-bolt form spacer in assembling a concrete form construction withoutnailing either the studs and sheathing, or walers. The invention is alsodirected to an improvement in a waler rod or she-bolt construction overthat as disclosed and claimed in my U.S. Patent No. 2,190,748 grantedFebruary 20, 1940 for a Securing Device for Concrete Forms and my U.S.Patent No. 2,048,- 151 granted July 21, 1936 for Concrete FormAppliances.

Prior to my invention it has been eustornary'to gauge the inner' end ofshe-bolts from the face of the sheathing to a predetermined depth byproviding the she-bolts with drilled holes to permit adjustment of 'theshe-bolt relative to the studding, which was assembled by nailing theshe-bolt to the studding in a predetermined position. In concrete work,where it is usually desired to assemble the forms at a predetermineddistance and to provide for re- Patented May 2, 1961 Still anotherobject'of the invention is to provide a she-bolt form spacer adapter foruse on waler rods or she-bolts, which pull out of the concrete ordisconnect back from the surface of the concrete to permit the reuseofthe she-bolts or waler rods.

Another object of the invention is to provide a shebolt form spacerwhich is adapted upon assembly of a she-bolt to the she-bolt form spacerto affix the she-bolt form spacer to the sheathing, and to permit thedisassembly of the she-bolt from the she-bolt form spacer, retaining theshe-bolt form spacer in position on the sheathing for reassemblyofshe-bolt's to the concrete form construction. V p

Another object of the invention is to provide an improved she-bolt formspacer for' use with la she-bolt clamp construction which maybe usedwith a nail in the stud, external spacing, or with an vinternal spacersuch as cones or washers bearing against the face of the form.

Still another object of the invention is the provision of she-bolt formspacers which are adapted for use with fastening devices for securingoppositely disposed form members together -by means operable either fromthe inside of the form or outside of the form.

Another object of the invention is the provision of an improved she-boltform spacer so that oppositelypositioned concrete form members may bespaced in their operative position by manipulation of fastening devicesfrom the outside of the form.

A further object of the invention is to provide an improved she-boltform spacer which would not become iilled with concrete and hinderremoval as Well as reuse.

Still another object of the invention is to provide an I improvedshe-bolt form spacer from sheet metal, permitmoval of the she-bolt fromthe intermediate tie rod, it

to permit the intermediate tie rod to be quickly, assembled totheopposite She-bolts, `allowing the same adjustment of the clampbrackets on the opposite faces of the forms.

In this manner the she-bolts and clamp brackets may be V assembled fromone side of the form and placed in position, and the opposite form withthe she-bolts brought in position and adjusted in place by adjustingeither the intermediate tie rod or the she-bolt to correctly space theforms.

Also, prior to my invention, it has been customary to assemble theconcrete forms by nailing the plywood sections or sheathing ldirectly tothe studs or walers. With the present invention it is possible toprevent the damaging eifect of nailing in dismantling or Wrecking theforms.

` It is, therefore, a principal object of the invention to provide animproved she-bolt form spacer overcoming the disadvantages of. the priorart constructions.

`Another object of the invention is to provide an improved she-bolt formspacer which may be readily assembled to she-bolts and to the sheathing,and studding forming the concreteform construction.

Another object of the invention is to provide an improved she-bolt formspacer which may be used on any standard form of threaded she-bolt orwaler rod construction. Y .t

A still further object of the invention is to provide a she-bolt formspacer which may be permanently afxed to the sheathing which permitsreuse of the sheathing without having to reattach the she-bolt formspacer to the sheathing.

A further object of the invention is to provide an improved concreteform construction formed from plywood Sections which permits assembly ofthe forms without nailing either the studs and sheathing or walersVto'provide an improved concrete form construction.

A still further object of the invention is to provide an improvedconcrete form construction for quick assembling and dismantling of theform members Without the damaging eiect thenailing has in Wrecking ofthe forms.

The invention also has among its objects'the production of improvedshe-bolt form spacers and concrete forms of the kind described which aresimple in construction, reliable, durable, economical, inexpensive,easily installed, and satisfactory for their purpose.

In order to accomplish the various objects of the invention, I haveprovided yan improved she-bolt form spacer may be easily mounted in theeld foruse .with a she-bolt to which itis assembled, and to the partsforming ,the concrete form construction such as Vthe studding'` andsheathing. The she-bolt form spacer formed in accordance with thisinvention is readily usable for the assembly of plywood sectionstogether withfwaler` rods, Vwaler rod supports, waler rod brackets,andstudding withoutnailing either the studs or walers. Concrete formconstruc-L tionsassembled in this manner, withthe use o f the she; f

bolt form spacer of this invention permit quick assembling anddismantling of the form members without the damaging effect the nailinghas in wrecking of the forms.

Many other objects and advantages of the she-bolt form spacer, theassembly of the she-bolt form spacer with concrete form constructions,and the advantages of the constructions herein shown and described willbe obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangementand combination of parts herein shown and described, and moreparticularly pointed out in the claims.

Referring now more particularly to the drawings, an improved she-boltform spacer 10 is illustrated, as shown assembled, on a she-boltconstruction, waler rod or form tie rod, or securing device 11 togetherwith a conventional form of clamping bracket 12 and adjusting nut 13assembled to sheathing 14, studding 15 and waler members 16 and 16', andassociated waler support brackets 17 to form-a conventional concreteform construction 18 for casting a wall or the like concreteconstruction with the forms 18 for forming thevopposite wall facesspaced apart by a tie rod 19 assembled to the free ends of the she-bolts11 to provide correct spacing of the forms for the desired wallthickness. Although the concrete form construction, as illustrated inFig. 1, may be conveniently formed by a plurality of oppositelypositioned form members 18 in which the sheathing 14 of each form isconnected by nails or the like with the exteriorly vertically extendingstuds 15, and the studs then being connected by the longitudinallyextending waler members 16, it is to be understood that it is within thescope of this invention that a similar concrete form construction, whichwill be disclosed later, with reference to Fig. 9 may be constructedfrom standard plywood sections without the use of nails.

Referring to Figs. l through 4, the she-bolt form spacer 16 issubstantially cylindrical in shape and at the end, to be positionedwithin the sheathing 14, is provided with axially extending lugs 20,preferably four in number, as illustrated in Figs. 4 and 5. These lugs20 are provided at their outer end with substantial radial or lateralprojections 21 which, as illustrated in Fig. 2, are adapted to beinserted in a hole 22 in the sheathing 14 and, as the she-bolt 11 isforced through the she-bolt form spacer, the prongs 21 move radiallyoutwardly and embed themselves within the sheathing, as illustrated inFigs. 3, 4 and 5. As the she-bolt 10 is also formed with the radiallyextending lugs 23, which serve as stop means to gauge the she-bolt formspacer with respect to the outer face of the sheathing, the she-boltform spacer is securely locked in position on the sheathing of the formas the she-bolt 11 is inserted, as shown in Fig. 3. The she-bolt formspacer may then only be removed from the sheathing by placing a suitabletool underneath the lugs 20 and forcing them radially inwardlysubstantially to the position shown in Fig. 2, after which it may thenbe detached from the sheathing.

Referring to Figs. l through 4, the she-bolt form spacer hasperipherally spaced axially extending slots 24 which are oppositelyformed to permit a securing means, such as a double-headed nail 25, tobe driven through the diametrically opposite slots and a hole 26 in theshe-bolt into the studding 15 after the forms 18 have been correctlyspaced for the required wall thickness to be poured. In erecting theshe-bolt form spacers 10 to the sheathing and the insertion of theshe-bolt 11 within the form spacer, it is preferable that they beerected, as shown in Figs. 1 and 2, so that the securing means 25 may beeasily affixed to the studding. However, this is not entirely essentialas long as the slots 24 and the hole 26 are aligned to the extent that anail may be driven to be secured into the studding. It is also to .benoted that the radially extending lugs 23, as shown in Figs. 3 and 5, bepositioned between the inner face of the studding and the sheathing 14.As the metal forming the form spacers is relatively thin, this hasrelatively little effect upon the abutting of the face of the sheathingto the studding since the face of the studding would slightly compressat the point, as illustrated in Fig. 3, where the lug is positionedbetween the studding and the sheathing. It is preferred to position theholes in the sheathing with respect to the studding as close aspossible, as illustrated in Figs. 3 and 5, although any slight variationwould have relatively small effect upon the rigidity of the assembledform.

A typical she-bolt form spacer adapted for use with a iV16 she-bolt isapproximately 35/16 in overall length and is formed from twenty-onegauge material. The slots 24 are approximately 1A wide and 21/2" long.The radial projection of the lug 23 is approximately 1% and that of theprong portion 21 is approximately 1/8. The axial spacing between thelugs 23 and the prongs 21 is approximately W16". It is to be understoodthat these dimensions are preferable for a EV16" .she-bolt and that aportion of the dimensions may be used for other dimensioned stay rodswhich, in some instances, on large form work may have a diameter of l,1% or 1%, depending upon the type of form and load to be supported bythe she-bolt construction. Although it is preferred to use this type ofshe-bolt form spacer with aligned forms for the assembly of forms forpouring walls, as illustrated in Fig. l, using a split r J walerconstruction, it is to be understood that the she-bolt form spacers mayalso be used with cantilever type formsV in which the studding is in theform of strongbacks. Usually, however, in the cantilever type of formconstruction, the Ashe-bolt is positioned to extend through thestrongback rather than being placed alongside of it.

Referring to Figs. 6, 7 and 8, there is illustrated the fabrication ofthe she-bolt form spacer from sheet material 30 in a progressive stepdie. In the rst step of the fabrication within the progressive stepdie,the portion A of the strip is formed with slots 24 and a modified 'slot24', so that as the strip is later cut oi along the edge of the slot asat 31 and 31', the completely formed she-bolt form spacer is adapted tobe formed into its substantially cylindrical shape. In this sameoperation the material is slit, as at 32 and 33, to form the lug 23which is substantially %2 across a face thereof. Alternating with thelugs 23 are the lugs'20, which are formed by a corresponding slit 32, sothat the face of this lug is substantially 1A. For

the particular 9/16" waler rod the first projection from the left ofFig. 6 is substantially 7/32 and thereafter alternate first 1A" and then3/16" withthe final lug at the right 20 being approximately 7/32 tocomplete the circumference for a W16 diameter waler rod of approximately1%". In the second step B in the fabrication within the progressive stepdie, referring to Figs. 6 and 8, the portions 34 from the first step areformed with a 9/32 radius to the shape 34', as illustrated in the step Bof Figs. 6 and 8, and this curvature corresponds to the radius of thewaler rod and extends throughout the length of the she-boltform spacerand is also formed on the lugs 20, the lugs intermediate being leftstraight, as illustrated at 23. In the nextstep C within the progressivestep die, the lugs and 23 are completed to their final shape, asillustrated in Fig. 7, with the lugs 20 having a taper correspondingsubstantially greater than the taper at the end of the shebolt. Theselugs 20 are tapered inwardly radially suiciently` that the projections21 may extend through the opening 22 inthe sheathing, as illustrated inFig. 2, to permit the insertion of the she-bolt 11 through the sheathingand at the same timeV as the she-bolt is inserted therein, theprojections 21 are forced into the peripheral edge of the opening 22,securing the she-bolt form spacer in position on the sheathing.

After the strip 30V has been progressively formed, as

illustrated in Figs. 6, 7 and 8, the strip is sheared off to form theprefabricated blanks C,` after which it is suitably formed to thecompleted Vshape of the she-bolt, as illustrated in the enlarged viewsof Figs. 2 through 5. As the die which fabricates the strip, asillustrated in the steps A, B and C,'is actuated during the pressoperation, the prefabricated strip C is sheared off, after which it maybe formed either in a separate machine to the completed shape or may 'beformed in the same press with suitable equipment if desired. It is alsowithin the scope of the invention that the sheared blank C may be leftin this shape-to be formed on the job about the she-bolt to which it ismounted with the workman using pliers or forming it by his hand, as thematerial isrrelatively thin and may be readily formed in this marmer.` Y

Referring to Figs. 1 and 9, there is illustrated two types of concreteform constructionswhich may be fabricated, using the she-bolt formspacer of my invention. Referring to Figs.Y lthrough 4, the sheathingmay be affixed in the normal manner to the studding 18 and placed in`position for erecting the form for the Wall to be poured, whereupon thelower walers y16 are supported upon the waler support members 117 which,in turn, have been affixed to the studding 18 as shown. The walersupport members are formed and erected as disclosed and claimed in myUnited StatesPatent fNo. 2,644,219, patented July 7, 1953. The she-bolt11 is then erected in place after the she-bolt form spacer has beenpositioned inv the sheathing, as described with reference to Figs. l, 2and 3 above. The upper waler member 16f .is then placed in position andthe clamping bracket 12 mounted on the she-bolt and the adjusting nut 13adjusted to the position shown. After this has been done, the nail issecured in position. The opposite form is erected in a similar manner,and the free inner ends of the she-bolts are connected together by a tierod 19, whereupon the opposite forms are correctly spaced for thethickness of the wall to be poured as is well `understood in the art.When the forms are dismantled the members are detached in the reverseorder and, if desired, the waler support brackets 17 may be pivotedinwardly after certain of the securing means are removed, the supportbracket being pivoted about the securing means 35'. The shebolts andshe-bolt form spacers may be retained in position, though usually theshe-bolts are Withdrawn so that they may not become damaged. Theshe-bolt form spacers 1t) are retained in position because of thelocking thereof in the sheathing 14, as illustrated in Figs. 3 and 4. Itis also within the scope of the invention that instead of placing thesecuring means inthe form of a doubleheaded nail 25 through the oppositeslots 24 in the shebolt form spacer 16 and through the hole 26 in theshebolt, a cotter key may be placed therein and, when this is done, thecotter key is so positioned that the location of the cotter key issubstantially 90 from the position of the double-headed nail, theshe-bolt 11 being rotated to permit'this. The cotter key is obviouslyspread and a double-headed nail 25 then may be driven through theopening in the head of the cotter key, securing the cotter key to thestudding and the cotter key, in turn, supporting the outer end of theshe-bolt form spacer and its cony nected she-bolt.

- Referring to Fig. 9, a concrete form may be constructed which may bereadily assembled and dismantled and in which the form members are notdamaged since they are not nailed. To erect a concrete form in thismanner,

a standard plywood panel 36, such as a 4' x 8' panel, is-

5. After the she-bolt form spacers and she-bolts are placed in position,and the clamp brackets 12 and adjusting nut 13 placed on the end of theshe-bolts, the

bottom walers 16 are placed in position and the waler support members 17are affixed in position, as illustrated in Fig. l. The upper walermembers 16 are then placed in position and the clamp brackets secured bythe adjusting nut. This assembly has been accomplished, using the endstuds with the she-bolt form spacers and corresponding she-bolts 11secured to the studs. As the shebolt form spacers are secured within theholes Z2 of the sheathing 14 provided by the panel 36 and are alsonailed to the studding, the studding or panel is rigidly aixed together.in place between the walers and sheathing without nailing. Succeedingpanels 37 and 38, as shown in the dotted lines, may be extended endwiseto the rst panel 35, and likewise, additional paneling 36', 37' and 38may be placed above. The form may be continued to be extended likewise,longitudinally or vertically, to provide the necessary length and heightof form desired, or likewise partition and/or building structure erectedin this manner. When the panels are dismantled, they are dismantled inthe reverse order and the waler support member 17 may be retained on thestuds 15, as described above, and the she-bolt form spacers 10' may beleft in the panels if desired, to assist in re-erection of the formsupon reuse.

Referring to Figs. lO'through 13, there is illustrated` Any additionalstudding 15' may be shoved trated as being directly affixed to thestudding 15 as illustrated in Fig. 3. This particular arrangement is notalways necessary since the walers 16 and 16 together With the sheathing14 are clamped together and alxed to the studding 15 by the clampingbracket 12 threaded on the she-bolt 11 since the projections 21 of theshebolt form spacer are expanded into the sheathing 14. In theparticular arrangement to be described, the shebolt form spacer andshe-bolt lare assembled to the sheathing 14 as described with referenceto Figs. 2, 3, and 4. Instead of having a nail 25 anxing the sheboltform spacer and she-bolt to the studding 15, the nail 25 or a cotter key40, Fig. 12, may be inserted through the slots 24 of the she-bolt formspacer and through the hole 26 in the she-bolt. If a nail is used, it isclinched over and it may be either a single or double-headed nail. Thecotter key 40 may, likewise, be suitably opened or self-opening cotterkeys may be used. In this manner, the sheathing 38 as described withreference to Fig. 9 may be assembled to studding 15, as described alsowith reference to Fig. 9, the difference being that the she-bolt formspacer may be spaced from the studding 15 or the auxiliary intermediatestudding 15' where the sheathing is in the form of large sheets ofplywood. Likewise, in removing the forms, the nails or cotter keys 40are detached to permit the shebolts 11 to be detached from the tie rods19, after which the clamping brackets 12. are returned to their originalposition, affixing the walers, studding, and sheathing together, and thenail 25' or cotter keys 40 replaced as described above. `In this manner,the concrete forms may be readily stored or reused as they are raisedfor pouring the successive lifts. n the event that they are entirelydismantled, the she-bolt form spacers 10 may still remain in thesheathing 38 for further reuse and, if still desirable, they can beremoved by bending the prongs 21 inwardly to the point that they may beremoved from the periphery of the hole 22 for the corresponding she-boltform spacer in the sheathing.

In the embodiment of Fig. 1l a modified form of shebolt form spacer 10'may be used with conventional forms 41 fabricated from metal sheathing42. When used in this manner, the radially extending lugs 23 may bewelded to the metal sheathing 42. If the metal forms 41 are used withouta wood or iiberboard form liner 43, the she-bolt form spacer 10 may beformed without the lugs 2li and the laterally extending projections 21.However, if the form liner is used with the metal sheathing, theconventional she-bolt form spacer may be used and the lugs and prongs 21are assembled through a hole 22 in the form liner 43 and metal sheathing42 as previously described with reference to Figs. 2, 3, and 4.

The form liner material 43 may be suitably bolted to the metal sheathing42 or it is Within the scope of the invention that suitable hardenednails 44 and washers 45, commercially available, may be used to assemblethe form liner material 43 to the metal sheathing 42, using aconventional explosive operated type hammer in which the nail ispropelled with an explosive charge. When erected in this manner, thepoint of the nail will project into the metal sheathing 42 since it ispreferred to use a nail formed from wire capable of being hardened topenetrate metal or other material. Erected in this manner, the formliner 43 is rmly aixed to the metal sheathing.

Referring to Figs. 12 and 13, there is illustrated another utilizationof the she-bolt form spacer of the invention for the erection of aconcrete form construction, using large plywood panels of sheathing andthe improved she-bolt form spacer. In this construction, the she-boltform spacers are symmetrically spaced on the panels, as illustrated inFig. 9, with the exception that the she-bolt form spacers arepreferabiyspaced transversely with respect to the studding 15. After theshebolts 11 have been erected in place and secured with cotter keys 40asdescribed above with Fig. l0 and theclamping brackets, waler supportmembers, and walers being erected as described with reference to Figs. land 9 and aflixed together, the next successive panel 38 may beassembled. It is preferred to use a securing means 48 as illustrated inFig. 13 for aiiixing the edges of contiguous panels together asillustrated in Fig. 12. The shank 49 is positioned between the joint ofcontiguous panels with its head Si) contacting the faces of the panels38 and 38' contiguous to their respective edges. Since the shank isformed With an eye 51 about the shank between the heads 52 and 53 of adoubleheaded nail 54, the nail is free to be inclined with respect tothe face of the stud 15 in which it is affixed so that, when drivencompletely into the stud, the head 50 forces the edges of the sheathing38 and 38 to abut the face of the studding' contiguous thereto asillustrated in Fig. l2. Although it is preferred to use an improved formof securing means as illustrated in Fig. 13 in this manner, it is alsowithin the scope of the invention that a commercial form of nail 54, asmanufactured by the Sierra Machine Company of Berkeley, California, mayalso be used without departing from the scope of this invention. Thistype of nail has a pointed hook portion 55 which is driven into the faceof the studding as illustrated, and is also provided with an integralhead 56 similar to the head 50 of applicants preferred form of securingmeans 48. Either of these types of securing means 48 or 54 permitswithdrawal from the studding without damage so that the studding may bereused. These securing means also permit the salvaging of the sheathing,since it is not necessary to remove nails which have been securedthrough the sheathing 38 directly into the edges of the studding.Although it is preferred to erect the panels solely without the use ofthe securing means 48 or 54, these securing means are advantageous inafxing the contiguous edges of the sheathing to the studding to preventundue warping of the sheathing. 'I'he successive panels of the form maybe erected as described with reference to Fig. l2, and if additionalstudding 15 are required these may be slid in place as described withreference to Fig. 9. Usually, in the erection of the securing means 48or 54, they are first loosely mounted over the edge and slightly atiixedto the studding. As the next panel is erected in place and tappeddownwardly to compress the edge of the panel where the shank of thesecuring means crosses, and also to place the panel back of the heads 50or 56, the securing means may then be firmly aixed in place to draw theedges of the panel in position and securely affix them to the studding.

It is thus evident that there has been disclosed a very simple formconstruction which may be readily erected without the usual damagingeffect caused by the nailing of the sheathing to the studding at thetime when it is desired to dismantle or wreck the forms for storage. Theonly nailing necessary is that required for mounting the support members17 to the studding and also that required for securing the she-bolt formspacer and she-bolt to the studding. These nails, however, may bereadily removed without damaging the studding. Likewise, when theshe-bolt form spacers 10 are detached from theA sheathing, this may bereadily accomplished by detaching the prongs 21 from the periphery ofthe holes 22, which causes very little or no damage.

It is thus evident that there has been disclosed a simple form ofshe-bolt form spacer which may be economically manufactured from lightgauge metal of the required strength for the associated she-bolt and theresultant she-bolt is low in cost, and may be readily erected eitherfrom a flat blank formed as described on the job or erected in placewhen fabricated originally in a cylindrical shape. The she-bolt may bereadily dismantled from the sheathing for reuse.

It is also evident that there has been disclosed a simple method oferecting forms and/or building structures, partitions and the like,using the conventional she-bolt clamps, waler members, walerrsupportmembers, studding and sheathing for forms of the ltype as illustrated inFig. 1 and as also erected by the method as described with reference toFig. 9, wherein the sheathingis assembled to the studding withoutnailing them together so that the forms may be quickly assembled anddismantled without the usual damaging effect of nailing. u

Having thus described my invention, it is obvious that variousimmaterial modifications may be made in the same without departing fromthe spirit of my invention; hence, I do not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described, or uses mentioned.
